TABLE AND STRAIGHTEDGE FOR TRIMMING PAPER.

Application filed September 4, 1924.' Serial No. 735,782. 2

To all whom it may concern:

Be it knownthat I, CHARLES E. GALVIN, a citizen of the United States, residing at Springfield, in the county of Clark and 5 State of Ohio, have invented certainnew and useful Improvements in Tables and Straightedges for Trimming Paper, of which the following is a specification.

This invention relates to a table and straight edge for trimming paper, particularly for use in connection with trimming wall paper, window shades and the like.

An object of the invention is to provide for hinging the straight edge to the table in 1 such a way that the straight edge may be maintained in parallelism with the table and be readily tilted out of the way to permit the paper or other article to be trimmed to be placed upon the table.

A further object of the invention is to .so construct the table that the straight edge may be tilted from one position to another while the cutting tool is on the straight edge.

Another object of the invention is to provide means for'hinging the straight edge and the table such that the parts may be readily assembled and taken apart.

In the accompanying drawings:

Fig. 1 is a top plan view of the table, straight edge and hinging devices.

Fig. 2 is an end view of the same.

Fig. 3 is a side view of the same.

Fig. 4 is a section on the line 4-4 of Fig. 1.

Fig. 5 is an end elevation of one set of the hinging devices.

Fig. 6 is an end view of the same.

Fig. 7 is a detail of the angle plate and connecting parts, the straight edge and table being broken away.

Referring to the drawings, 1 and 1 represent the two parts of the top of the table which may be hinged together to permit the table to be folded in a well known way. The table top is supported by hinged legs 2 and hinged braces 4 of usualform. In the present case the forward edge of the part 1 of the table top overhangs the frame member 3, as shown in Fig. 4, and the ends of the forward edge of this part 1 are recessed as indicated at 5 in Figs. 1 and 3 for a purpose to be explained. The straight edge is indicated at 6 and is of the usual form, being provided with a longitudinally. extending grooveway 7 on its upper surface near its forward edge and with a metallicplate 8 which overhangs the grooveway for the purpose of guiding and retaining the cutting tool thereon in a manner common to devices of this character In Fig. 4 I have shown a cutting tool which is adaptable for the purpose, this tool being more fully described in another copending application. 9 represents a frame or head which carries a cutting disk 10, and 11 is'another cutting disk, the arbor of which is journaled in a boss 12 at the forward end of an arm which has its rear end pivoted to the downwardly-projecting extension 13 of the frame in a manner fully described in said application. A spring (not shown) holds the disk 11 in yielding engagement with the underside of the straight edge. A gauge strip 13 secured to the head 9 has laterally-projecting lips 14, which project beneath the under side of the metallic strip 8.

The straight edge is hinged to the table in the following manner: Secured to each end of the table is a metallic plate 15 which has a pair of laterally projecting studs 16, these strips, serving merely the purpose of reinforcing the wooden table ends and as a convenient means of securing the studs thereto.

Another metallic plate 1.7 is inserted on these studs and clamped to the plate .15 by nuts 18, this plate 17 projecting forwardly beyond the forwardv edge of the table. Hinged to the forward end of this plate 17 by a bolt 19 is an arm 20 which carries a series of headed studs or screws 21 which pass through slotted openings 22 in the vertical portion 23 of an angle plate. The horizontal portion 2410f this angle plate is apertured to receive a stud 25 embedded in and projecting upwardly from thestraight edge, the stud being threaded to receive a wing nut 26 whereby the horizontal portion of the angle plate can be clamped to the straight edge.

In operation, the straight edge normally lies on the table in the position shown in the drawings slightly overhanging the forward edge of the table as shown in Fig. 1. The paper is placed on the table beneath the straight edge and when the cutting tool is slid along the straight edge the lower cutting disk forces the paper against the lower surface of the straight edge so as to firmly hold the paper during the cutting operation as fully described in co-pending application Serial No. 735,783. When it is desired to place a new piece of paper upon the table, the straight edge is swung to the position shown in dotted lines in Fig. 2 and there after tilted back to" its operative position upon the paper. For the purpose of enabling the operator to straighten the paper beneath the straight edge each end of the straight edge may be raised slightly due to the slotted openings 22. When it is desired to transport the table and straight edge the thumb nuts 26 are removed so as to free the straight edge from the angle plates and the nuts 16 removed to free the plates 17 from the plates 15 so that the table may be then folded and the straight edge and hinging devices all packed in a suitable box for the purpose.

Having thus described my invention, I claim:

1. In an apparatus of the character de scribed, the combination of a table and a straight edge, with devices for holding said straight edge to said table in predetermined parallel relation to the forward edge of the table, and means for hinging said holding devices to permit them to swing substantially in the arc of a circle, whereby the straight edge may be temporarily swung laterally to remove same from. the table while i'i' aintaining the predetermined paral lel relation of said table and straight edge 2. In an apparatus of the character de scribed, the combination with a table and straight edge, holding devices for said straight edge to maintain the straight edge in predetermined parallel relation with the edge of the table, said holding devices being pivotally mounted to permit the straight edge to be swung on said pivot into various posit-ions for removing same from the table, while maintaining the parallel relation between said straight edge and said table throughout the various movements of said straight edge.

3; In an apparatus of the character described, the combination, with a table and a straight edge, of an arm hinged at each end of said table and projecting forwardly, and means for connecting each end of the straight edge to one of said arms whereby when in operative position the straight edge lies on the forward edge of the upper face of said table, but may be temporarily swung on said arms forwardly and down wardly to clear the table top.

4. In an apparatus of the character described, the combination, with a table and a straight edge, of a pair of arms pivot-ally. connected with the ends of said table, of a straight edge connected with said arms, said straight edge when said arms are in horizontal position lying on the forward edge of the upper surface of said table, said arn'is when swung on their pivotal points carr ing said straight edge forwardly and downwardly to clear said table.

5. In an apparatus of the character de scribed, the combination with a table and straight edge, of a pair of metallic plates secured to the ends of said table and projecting forwardly beyond the forward edge of said table, of a pair of arms pivotally connected with the forward ends of said plates, and means for connecting the straight edge with the free ends of said arms.

6. In an apparatus of the character described, the combination, with a table and straight edge, of a plate secured to each end of said table, a second plate removably connected with each of said first plates and projecting forwardly beyond the forward edge of the table, an arm pivotally connected with the forward end of each of said second plates, and a straight edge secured to the plates being such as to permit a limited raising movement of said straight edge with respect to said table.

In testimony whereof I have hereunto set my hand this 26 day of August 1924.

CHARLES E. GALVIN.
